A pseudo-Germanic conglomeration, with meaning roughly similar to "shit-storm."

Internet persona(s) who happens to follow you and you happen to follow them back and maintain communication with and have a mutual liking for eachother whether it be friendship wise, etc. (Mutuals if more than one mutual)

A large quantity of feces output in a considerably short window of time.

When birds decide to cover something in shit (Preferably something that is new/shiny/just been cleaned), they will declare Shitskrieg upon it, and start dive-bombing it, plastering any and all surfaces with faeces.

Basically, it's like Angry Birds, only with poop.
